C11000 Pure Copper is a purple red metal, commonly known as "red copper". It is malleable. It as the size of a drop of water can be pulled into filaments up to two kilometers long or rolled into almost transparent foil larger than a bed. The most valuable property of C11000 is that it conducts electricity very well, so it has become the "leading role" of the electrical industry.
The applications of C11000 is much more extensive than iron, 50% of Cu is purified into pure copper by electrolysis every year, used in the electrical industry. Normally very small amounts of impurities, such as phosphorus, arsenic, aluminum, etc., will greatly reduce the conductivity of copper. Oxygen in copper (copper smelting is easy to mix with a small amount of oxygen) also has a great impact on conductivity, so the Cu used in the electrical industry must generally be oxygen-free copper. In addition, lead, antimony, bismuth and other impurities will make the crystallization of copper can not be combined together, resulting in hot brittle, will also affect the processing of C11000.
This kind of copper with high purity is generally refined by electrolysis: the impure copper (coarse copper) as the anode, C11000 as the cathode, and copper sulfate solution as the electrolyte. When the current passes through, the impurity copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. Copper obtained by such refinement; The purity can reach 99.99%.
Copper has good electrical conductivity and great plasticity.

C11000 Pure Copper, commonly referred to as "red copper", is a highly malleable purple-red metal. It is highly valued in industrial applications, particularly within the electrical industry, due to its exceptional electrical conductivity.
It is refined using an electrolysis process where impure copper serves as the anode, C11000 acts as the cathode, and a copper sulfate solution is used as the electrolyte. This process achieves a copper purity level of up to 99.99%.
C11000 Pure Copper features a tensile strength of ≥260 MPa, a yield strength of ≥205 MPa, and an elongation percentage of ≥12%.
Even trace impurities like phosphorus, arsenic, and aluminum can significantly decrease its electrical conductivity. Other impurities such as lead, antimony, and bismuth can prevent proper crystallization, resulting in hot shortness (brittleness) and poor processing characteristics.
C11000 has excellent hot forming capabilities within a temperature range of 750°C to 875°C, and it can be annealed at temperatures between 425°C and 650°C. Its softening temperature is 350°C.
